CHANGEABLE SIGN.

' Specification of Letters Patent.

Patented Oct. 21, 1919.

Application filed January 22, 1919. Serial No. 272,462.

To all whom it may concern:

Be it known that I, HAROLD C. Connenovn, a citizen of the United States, residin at Detroit, in the county of Wayne and tate of Michigan, have invented a new and useful Changeable Sign, of which the following is a specification.

This invention relates to changeable si ns and has particular reference to changea le signs having frames of sectional construction, such as to permit the size of the sign to be varied.

It is the object of the invention to provide a si n having its frame comprised of tubular sectlons, adapted to be expeditiously tel..- scopically engaged or disengaged, said sections being slotted to receive the Sign plates and also to render the engaging end portions resiliently expansible and contractlble so as I to facilitate their ready assembly or disassembly.

The provision of means to insure registration of all of. the slots of the several sections when the same are assembled to form the frame is a further feature of the inven.

tion, the same means preferably serving also to prevent accidental disengagement of the sections.

In attaining these ob ects the invention contemplates a sectional sign frame formed of tubular units, each having one extremity so reduced in diameter that it will snugly fit within the unreduced end of an adjoining section, the unitsor sections be1ng slotted from end to end to receive sectlonal sign plates andhaving their telescopically engaging portions formed with corresponding peripheral projections and depressions which interengage When the sections are telescopically connected.

A preferred embodiment of the invention is illustrated in the accompanying drawings, wherein,

Figure 1 1s a front view of the sign, showing thelower portion of the frame in sectime.

Fig. 2 is a perspective view of several sections of the sign frame in disassambled relation.

Fig. 3 is an enlarged view of the sign in cross-section, the section being taken upon line 3-3 of Fig. 1.

' In these views the reference character 1 designates a plurality of sign plates, each numbers. Said plates are adapted to be I mounted in a sectional frame comprising a plurality of intermediate tubular members 2 and a pair of end tubular members 3. Each of said members is sufficiently reduced in diameter at one end, 1, to fit snugly within the unreduced end of an adjoining frame member. The members 2 are straight and the members 3 approximately U-shaped.

Thus While the length of the sign frame may be greatly varied, the height of said frame 1s maintained constant by the end members 3. It is apparent, however, that the end members might be formed of sections similar to those constituting the top and bottom members of the frame,'in case it were desired to provide for variations in the height as well as in the length of the frame.

Each of the members 2 and 3 is slotted from end to end as indicated at 5, the slots being proportioned in width to receive the marginal edges of the plates 1. Furthermore, each of said members has a peripheral teat or punch-prick 6 upon its reduced end portion which is adapted to fit snugly into an indentation 7 formed interiorly in the unreduced end portion of an adjoining section, when said adjoining sections are telescopically engaged. The parts 6 and 7 are so located with reference to the slots 5 that registration of the slots in adjoining sections is established and maintained when said parts are engaged. It is evident also that telescopic engagement of the sections is maintained through the engagement of parts 6 and 7. The slotted construction of the sections permits the same to undergo a slight circumferential expansion when. telescopic engagement is being established so that the projection 6 does not prevent establishment of such engagement.

In putting together two adjoining sections and the two sections may be then relatively rotated to introduce said projection 6' into the indentation 7 of the other member.

Obviously by using more or less ofthe sections 2, the length of the sign frame may be increased or diminished to any desired extent.

What I claim is:

1. A sign comprising a plurality of sign plates, and a frame forsaid lates consisting of telescopically engage tubular sec reduced end portion of an adjoining section, said sections being slotted longitudinally to receive marginal portions of the plates, the telescopically engaged portions of the sections being respectively formed with a projection and an indentation receiving said projection, said indentation and projection being located with reference to the slots of said sections to insure registration of said slots when interengaged.

In testimony whereof I sign this specification.

HAROLD G. COLEGROVE.
